envelope complexreadily undergoes receptor-activated The human immunodeficiency virus type 1 (HIV-1) is conformational change suggests that its native state is an enveloped virus, and its envelope protein complex metastable, again similar to the pH-activated envelope controls the key process of viral entry. This envelope protein of influenza virus (Carr et al., 1997). That is, protein determine...

of N. coenophialum mycelial proteins was first proposed by Gwinn et al. (1991) using polyclonal antiserum proA reliable, efficient, and accurate detection method for presence duced in rabbits. This technique worked equally well of the endophytic fungus Neotyphodium coenophialum (MorganJones and Gams) Glenn, Bacon, and Hanlin comb. nov. in tall fescue with either seed or plant tissue but seed an...

rejected? Why don’t all females make anti-sperm antibodies S (equivalent to glycodelin A but in seminal plasma) Clark when inseminated with spermatozoa? These fundamental quesprovides evidence that both forms of glycodelin contain tions, which present difficult intellectual and experimental immunosuppressive moieties that are mimicked by pathogenic challenges to the scientist, are yet to be res...

erates frequent defoliation in monoculture (Peterson et al., 1994) or in binary mixture with grass (Kim, 1996) Improved dry matter (DM) production of cool-season grass monoand is suitable for hay or pasture production in this cultures may result from either N fertilization or the addition of legumes such as kura clover (Trifolium ambiguum M. Bieb.) or birdsregion (Sheaffer and Marten, 1991; She...

Arachidonic acid (AA) can be metabolized to various metabolites, which can act as mediators of cellular processes. The objective of this work was to identify whether AA, prostaglandin (PG) B 1 and E 2 , and 15and 20-hydroxyeicosatetraenoic acids (15and 20-HETE) are metabolized via glucuronidation. Assays with human recombinant UDP-glucuronosyltransferase 1A (UGT1A) isoforms revealed that AA and...

cDNA and genomic clones encoding DNA topoisomerase I were isolated from Arabidopsis thaliana Xgtl1 and XFix libraries by low stringency hybridization with a Saccharomyces cerevisiae TOPi probe. The cDNA clones include a 2748-base pair open reading frame predicting an amino acid sequence that is highly homologous to sequences encoded by TOP1 from yeast and human sources. The sequence of the upst...

Polarizations from proton fragmentation are compared to determine the dependence on produced hyperon according to energy, target and kinematics. Polarization data for meson and neutrino beams are also given. Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jphyscol:1985212 C2-122 JOURNAL DE PHYSIQUE There are many reasons for studying hyperon production. Hyper...

To enhance international competitiveness through the protection of cutting-edge industrial technology, it is essential to establish the policy for strengthening ability to develop industrial security technology and raising international competitiveness. In this study we investigated and analyzed not only the ecumenic trend but also the present condition, then we executed the deduction of the in...

ion is implemented by the operating system extended with the language runtime support that manages the name space of agents and the interactions among different agents. Agent Tcl EUs can either submit a new agent to a remote site or migrate to another site. In the first case, the EU provides the code to be executed remotely by a newly created EU. In addition, the programmer can specify explicit...
